Increased ALP activity is associated with two groups of diseases: those affecting liver function and those involving osteoblastic activity in the bones. (cdc.gov)

Postoperative myocardial infarction (MI) and angina have a peak incidence during the first 3 postoperative days but may occur for up to 5 days. (medscape.com)
By 1963, Dr. William Bruce, aware of the tendency of people with coronary artery disease to experience angina (cardiac chest discomfort) during exercise, developed the first standardized method of "stressing" the heart, where serial measurements of changes in blood pressure, heart rate and electrocardiographic (ECG/EKG) changes could be measured under "stress-stress" conditions.

Our findings suggest that empagliflozin enters cardiac mitochondria and directly causes these effects by increasing mitochondrial ATP via inhibition of NHE1 and Nav1.5 or their common downstream sites. (nature.com)
These findings give new insights into cardiac adaptation to endurance training and could also be of use for sports cardiologists evaluating female athletes. (bmj.com)

Apical left ventricular (LV) dyskinesis (ventricular aneurysm) after an anterior myocardial infarction. (medscape.com)
Myocardial strain and strain-rate have appeared as quantitative parameters to solve the high variability of left ventricular wall thickening evaluation (1). (escardio.org)
After indexing by cardiac length, s′ was only higher in ATH in the mid-ventricular septum (p=0.041). (bmj.com)
BACKGROUND: Acromegaly is associated with an increased left ventricular (LV) mass, as reported in echo-based and, more recently, in a few cardiac magnetic resonance imaging (MRI) studies. (bvsalud.org)

Cardiac imaging refers to minimally invasive imaging of the heart using ultrasound , magnetic resonance imaging (MRI), computed tomography (CT), or nuclear medicine (NM) imaging with PET or SPECT . (wikipedia.org)

The occurrence of myocardial infarction (MI) in men is expected earlier and with higher severity compared to age-matched women [ 1 ]. (biomedcentral.com)
